Sunderland are to join the chase for former Chelsea striker Salomon Kalou who they want on a permanent deal, according to The Sunderland Echo.
The North-East side are one of several clubs, including Premier League side West Ham, that want the Lille forward.
It is believed the French club want £4 million for Kalou which is within The Black Cats budget.
However speaking after the 1-1 draw with Manchester United, Sunderland manager Gus Poyet gave no indication towards the potential signing the French international.
“I am going to have to do research at this football club into who is leaking information every week. It cannot be always the player’s agent,” he said, speaking to Sunderland Echo.
“A few agents, okay, you can blame them, but there is too much information coming out and I don’t like it.
“I am not going to comment on any players, sorry.”
The 29-year-old spent six seasons at Chelsea, scoring 60 goals in 251 appearances before moving to Lille but now could be on his way to England.
